Abstract

The invention discloses a double-power automatic transfer switch which comprises a mounting seat, as well as a double-power contact terminal system, a switch mechanism and an operating mechanism which are arranged in the mounting seat, wherein the double-power contact terminal system comprises a main power source wire-in terminal, an auxiliary power source wire-in terminal, a load wire-out terminal, a main static contact connected with the main power source wire-in terminal, an auxiliary static contact connected with the auxiliary power source wire-in terminal, a driving contact terminal rotationally arranged on the mounting seat, and an auxiliary movable contact rotationally arranged on the mounting seat; the main power source wire-in terminal, the auxiliary power source wire-in terminal, and the load wire-out terminal are arranged at the same side end of the mounting seat; the load wire-out terminal is arranged between the main power source wire-in terminal and the auxiliary power source wire-in terminal; and the operating mechanism is arranged at the other side end of the mounting seat. According to the double-power automatic transfer switch provided by the invention, the load terminals of the normal power source and the stand-by power source are shared, so as to form an integral body part; and the structure is more reasonable and compact, the performance is comparatively better, and the conversion reliability is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of structural design of low-voltage electrical appliances, and in particular relates to a dual-power automatic transfer switch. Background technique [0002] The most important performance indicators of automatic transfer switching devices are short-circuit making capacity, short-circuit breaking capacity, electrical life and mechanical life, and the structure of switching devices is directly related to the effect of performance indicators. The traditional automatic transfer switch electrical appliances with specifications above 630A use a double-mechanism or double-electromagnet interlocking structure. The disadvantage is that when the double-mechanism transmission is used, the parts are complex in structure, and the coordination accuracy of each part is required to be high, and failures occur. The number of times is many; the double electromagnet interlocking structure needs to be powered by the electromag...
